After successfully checkin still i can't see sift attendance report

After successfully checkin still i can’t see the Employee’s Present / Absent in shift attendance report?

Report worked based on the Attendance doctype and also Attendance have in_time and out_time details after then report will work.

I have did shift type then shift assignment foe all employees. but when i want to see shift attendance i can not see. Am i missing something.
Do i need to do shift request & Shift Assignment Schedule for everyone indivisuly.

Infact, i can see yesterday’s chekin in and check out timing but if i clki on shift attenadnce its not showing present/absent status. why

Please explain the steps
